Multiquip 29504 Thermal Switch 230°F - OEM Replacement Part

This thermal switch is a critical safety component that monitors engine temperature on Multiquip ride-on trowels, automatically shutting down the system when temperatures reach 230°F to prevent engine damage and costly overheating failures. Installed in the wiring harness of the HTX-44K and HTX-44K/Y ride-on trowel models, this switch acts as a fail-safe protection device during extended operation or when cooling system issues arise.

When the thermal switch activates, it interrupts power to protect the engine from catastrophic damage due to excessive heat. Common symptoms of a failed thermal switch include unexpected shutdowns at normal operating temperatures, failure to shut down during actual overheating conditions, or intermittent electrical issues in the trowel's control system. Regular inspection of this component during routine maintenance helps ensure reliable operation and prevents expensive engine repairs.

Compatible with the following Multiquip models:

• HTX-44K4
